Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at Difference Between Speed and Velocity. . We can find the movement of an object with the calculation of distance completed by an object in a given time interval called speed. The speed is sometimes considered similar to the velocity since these 2 have some similarities. But these are different parameters of motion in science.
Velocity is a calculation of the distance covered by a body in a certain direction. In today’s post, we will have a detailed look at both these factors of motion and their relationship with each other. So let’s get started with the Difference between Speed and Velocity.
Difference between Speed and Velocity
Speed
- Distance traveled by an object in unit time is called speed.
- Speed tells about how fast someone is moving.
- It is a scalar quantity.
- the speed formula is s=d/t here s is speed d distance t time
- its dimensiosn is M0L1T-1
- main 4 types it has
- uniform, average, instantaneous, variable
- equal distance in equal time called uniform speed
- same time is taken to cover different distances called variable
- total distance to total time ratio called average speed
- Speed taken at any time is called instant speed
- A speedometer is used to speed measurements.
- It denoted the rapidity of a body.
- It is a rate of change of distance.
- If the body covers some distance and moves back to the original position its distance speed will not be zero.
- The speed of moving bodies is not 0.
- Its SI unit m/s.
- Anybody can have different velocities but has the same speed.
Velocity
- The rate of change in the position of the body with time is called velocity.
- It is equivalent to the body speed feature having direction and movement.
- It is mostly used in the science field of kinematics.
- It is a physical term that has velocity tan magnitude.
- Its unit is m/s other units are ft/s, km/h
- Average velocity is Δv=Δx/Δt
- angular velocity is ω=Δθ/Δt
- If the body has zero distance its velocity is zero velocity
- The velocity measured between two objects is called relative velocity.
- Its dimension is LT−1
- The moving body has zero value of speed
- A change in velocity called acceleration
- Speed measured at any instant of moving object is called instantaneous speed
- The product of mass and velocity is equal to the momentum.
- It is a vector quantity.
- It denoted the rapidity and location of a body.
- It is the rate of change of displacement.
- If the body covers some distance and comes to its original position its velocity will be 0.
- The velocity of moving bodies can be negative, positive or 0.
- Its system international unit is m/s.
Speed vs Velocity
- Speed is a scalar quantity and has magnitude, not direction.
- Velocity is a vector and comes with both magnitude and direction.
- Speed measures the distance covered by the body with time and velocity measures magnitude and direction.
- Speed is employed for measuring time and distance during traveling. While velocity is used in vector mechanics and dynamics physics.
- Speedometer used for measuring speed and velocity measured with vector displacement on time.
What is different between speed and velocity?
- Speed defines the body’s change in distance with time and velocity is a change in displacement with time.
What are 5 examples of velocity?
- Rotation of earth about the sun
- Vehicle speed.
- Train moving speed.
- Rivier moving with a fluctuating speed.
- Speed of bat striking ball.
What is the correct relationship between velocity and speed?
- Speed is the measuring of distance covered for a certain time and velocity is displacement over time. Speed is the same as velocity when the direction of motion is a straight line.
What is the formula for velocity and speed?
- Velocity is a vector quantity that finds the value of displacement with time. That is denoted as v = Δs/Δt.
- Speed is a scalar quantity that measures the distance covered with time denoted as r = d/Δt.
Is the speedometer a scalar?
- The speedometer is a device that comes with the instantaneous speed of the object. The speed is a scalar quantity and we can say that the speedometer measures a scalar quantity.
